[drm:intel_enable_lvds]*ERROR* timed out waiting for panel to power on

I get this error when I start mystem. I've only just joined Arch. I have been using a multi-boot system. Ubuntu, Win7, Arch.I deleted everything. However, I am the whole day to install arch, without susccess.

May be due to grub?Syslinux would be better?Do I really need a bootloader? As I have only one OS.
